How to add a nixvim flake like a module in my nixos config

[basilgood]

Hi, thanks for your work.
I have a repo: flake.nix

  inputs.nixvim.url = "github:nix-community/nixvim";
  inputs.flake-utils.url = "github:numtide/flake-utils";

  outputs = {
    self,
    nixpkgs,
    nixvim,
    flake-utils,
  }: let
    pkgs = nixpkgs.legacyPackages."x86_64-linux";
    config = {
      colorschemes.kanagawa = {
        enable = true;
        terminalColors = false;
        commentStyle = {italic = false;};
        keywordStyle = {italic = false;};
      };

      plugins.lualine = {
        enable = true;
        refresh.statusline = 0;
        componentSeparators = {
          left = "";
          right = "";
        };
        sectionSeparators = {
          left = "";
          right = "";
        };
        sections = {
          lualine_b = [{name = "diagnostics";}];
          lualine_c = [
            {
              name = "filename";
            }
          ];
          lualine_x = [{name = "filetype";}];
        };
      };
  in
    flake-utils.lib.eachDefaultSystem (system: let
      nixvim' = nixvim.legacyPackages."x86_64-linux";
      nvim = nixvim'.makeNixvim config;
    in {
      packages = {
        inherit nvim;
        default = nvim;
      };
    });

I added input nixvim in my nixos config flake:

    nixvim = {
      url = "github:repo/my-nixvim-flake";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = inputs @ {
    self,
    nixpkgs,
    home-manager,
    nixvim,
    ...
  }: {

How to add a module in my config to replace pkgs.neovim with pkgs.nixvim ?

Ok, so if I understand correctly, you have a standalone flake for your nixvim configuration.
Running nix run in this repo runs your customized neovim.

Now what you want to do is to use this resulting package in your configuration (home-manager or NixOS) right ?
If the system configuration also lives as a flake output, then, add your nixvim flake as input.
Then, add inputs.nixvim.packages."${system}".nvim to your systemPackages or home.packages list.

It works perfectly. Thank you very much.

            home-manager.users.yourname.home.packages = [
              inputs.nixvim.packages."${system}".nvim
            ];
